One of my dreams is to do a one-arm pullup.
我的梦想之一是单手垂挂。
This constant defines the port on which the pullup resistor is connected.
这个常量定义了上拉电阻是连接到哪个口的。
Omit resistor R3 if IC2 includes built-in pullup resistors, as do many modern microcontrollers.
如果IC2包括内置的上拉电阻，就可以忽略电阻r 3，许多现代微处理器都是这样的。
It is the responsibility of the host designer to connect external pullup resistors to those lines.
主机设计者有责任给这些连接线加上外接的上拉电阻。
The selected function for the GP3/MCLR pin is input, and you must enable the global weak-pullup bit in the microcontroller's configuration word.
GP3/MCLR管脚的 可选功能为输入，在微处理器配置命令中，必须使能全局弱上拉位。
I fly the aircraft back down to the 1,500-foot line at 500 feet and modify my airspeed to get at show center for the pullup. I level off at about 500 feet.
我在500英尺高度上把飞机飞回到1500英尺标线处，并且调整我的空速准备飞到展览中心上空时拉起，在大约500英尺标线处我把飞机改平。
Because the positive side of C1 cannot instantly change its polarity, it pulls low and slowly charges up again through the internal pullup resistor of the input.
而C1的正向不能立即改变极性，其被拉低并通过输入的内部上拉电阻，缓慢的再次充电。
Because the positive side of C1 cannot instantly change its polarity, it pulls low and slowly charges up again through the internal pullup resistor of the input.
而C1的正向不能立即改变极性，其被拉低并通过输入的内部上拉电阻，缓慢的再次充电。
